分なものではない。(b) Conventional technology and problems Conventionally, nickel hydroxide electrodes are produced by immersing a porous nickel substrate, such as a sintered porous nickel substrate, in an impregnating solution of an aqueous nickel nitrate solution, and then hydrating the nickel nitrate in an aqueous alkaline solution. It is manufactured by repeating the process of converting it into active material and producing the required amount of active material. In order to increase the active material 'α optical filler of one cycle saD in the above process and reduce the impregnation, a very highly concentrated aqueous solution of nickel nitrate hexahydrate is used as the impregnating liquid, and its viscosity is reduced. In order to do this, a method of immersion at a high temperature of 60° C. or higher is widely used. However, this method results in a high concentration of free nitric acid in the aqueous nickel nitrate solution and a high lF concentration.
A, the nickel substrate was corroded and the strength of the electrode plate and electrode performance were reduced. Therefore, in order to suppress this corrosion, a method of forming a nickel oxide film on the surface of a nickel substrate is disclosed in Japanese Patent Application Laid-Open No. 59-78457.
(Japanese Unexamined Patent Publication No. 59-96659, etc.), but their effects are not sufficient.

When metallic nickel or nickel hydroxide is immersed in a high-temperature acidic nickel nitrate aqueous solution, free nitric acid is dissolved until it is consumed, and the pII of the aqueous solution increases. However, as a result of detailed research into this phenomenon, the inventor of the present invention discovered the following phenomenon.

たのである。That is, when the pH of the aqueous solution is adjusted to 1 to 2, the dissolution phenomenon does not proceed significantly even at high temperatures, and on the contrary, a precipitate is formed.When this precipitate was subjected to X-ray diffraction analysis, it was found that N12
(OH)2(NO3)2.2H20, and it was also found that this product is very stable even at high temperatures of 60℃ or higher as long as the pH is 1 or higher. It is.

法を提供するものである。The present invention was made based on the above findings, and includes a method for manufacturing a nickel hydroxide electrode for an alkaline storage battery, in which the nickel hydroxide electrode is filled into the nickel substrate in a required amount by repeating the washing and drying process. The present invention provides a method for producing a nickel hydroxide electrode for an alkaline storage battery, characterized in that the temperature is about 60 to 100°C and the pH is about 1 to 2.

。The porous nickel substrate used in this invention may be one that is normally used for electrodes of alkaline storage batteries, such as a slurry consisting of carbonyl nickel powder, water, a binder such as methylcellulose, and a pore-forming agent. Examples include those manufactured by coating both sides of a nickel-plated steel plate, drying, and sintering in a reducing atmosphere.

して含浸は約60〜100℃でかつpHは約1〜2で行
われる。In this invention, a high humidity solution having a specific gravity of approximately 1.7 to 1.8 is suitable as the nickel nitrate aqueous solution. The impregnation is then carried out at a temperature of about 60-100°C and a pH of about 1-2.

極板のニッケルおよび活物質の水酸化ニッケルの硝酸ニ
ッケル水溶液の含浸液への溶出液が急激に上昇するので
好ましくない。If the temperature of the impregnating liquid is not about 60°C or higher, the viscosity will be high, and if it exceeds 100°C, the amount of evaporation of the impregnating liquid will be large, and the pH will be adjusted to [01]. In addition, outside the pH range of about 1 to 2,
This is not preferable because the elution of nickel from the electrode plate and nickel hydroxide from the active material into the impregnating solution of the nickel nitrate aqueous solution rises rapidly.

表面にN12(OH)2(N08)2・2H20の皮膜
が形成され含浸液に対して不働態化して耐腐蝕性を示す
ものと考えられる。This is because when the pH of the impregnating liquid is adjusted to 1 to 2, a film of N12(OH)2(N08)2.2H20 is formed on the surface of the electrode plate, which becomes passivated to the impregnating liquid and becomes corrosion resistant. This is considered to indicate that

うために、PHの調整は硝酸と水酸化ニッケルとを添加
することによって行うのが好ましい。In addition, the pH of the impregnating solution can be adjusted using ordinary acids and alkalis, but in order to easily manage the impregnating solution, such as the concentration of the solution, the pH can be adjusted by adding nitric acid and nickel hydroxide. It is preferable to carry out by.
